Synergistic Red Fuse ...

David, 
That's terrific regarding the flexibility of your amplifier towards 300bs. You're in store for much  fun with these various tubes to listen to,
Charles, 

I just talked to Ted Denny and he says this stuff really doesn't do anything and no real research was involved other that some marketing ideas.  He says enjoys reaping a pile of money from the "seekers' who are seemingly born every minute, and apologizes to those who have found his products to be useless…he has issued a resounding "meh." 

Hi David,  
I know that you drive your Tersonic speakers with your 45 SET.  Have you tried the 300b amplifer with these speakers?
Thanks, 
Charles, 

Awhile back I asked if anyone had put an SR fuse in their conditioner OregonPapa responded,

Fourwnds ...

So far, no one has reported trying an SR fuse in their power conditioner. Why not be the first, then report the results here? I'd certainly be interested in the results.

I recently took advantage of the sale on the SR20 fuses and put one in the conditioner and one in each mono block replacing standard glass fuses.  It was a little over 100 bucks with shipping. So less than the price of one Black. I figured it was a good way to go and establish a baseline. It was. Except I didnt have the patience to put fuses in a step at a time evaluating the incremental changes. I just went for it, time is precious. Anyway, down to the nitty gritty, or more aptly to the lack thereof. The bass is so clean and full now is the biggest improvement. Before it could be on the ripe side. Now it's so distinct I can follow it with no extra attention. Overall it's a similar across the board improvement but to a lesser degre, with faster cleaner notes, keys sound purer and cymbal shimmer has more texture, there are more little noticible details bringing you in but with no etch. In fact this has been tamed on a few hot recordings where a violin could be shrill or a horn could have a little to much bite.  Spatial layering is better to.
Interestingly, I knew I wasn't sending these puppies back and it was gonna be awesome from the second the needle dropped as the gentlemen introduced the band it was as if it was a live direct patch from his mouth to my ears. I could hear his lips and I could tell they were wet like he licked them or he just took a sip from a drink.  
But, this little artifact aside it's like these fuses take what you have and make it better, changing the overall gestalt positively. It's not an additive thing like putting a little salt on something but more like the ol cliche of a cleaner window. Also, It is Not an improvement that is something of a compromise either where I lost something to get something else. 

I can't imagine the difference the Blacks would make. From what understand the highs are what get an improvement. 

Cheers all

Four winds,
I'm happy for your  positive results.  I began with the SR 20 Quantum fuses four years ago purely out of curiosity and was delighted with the outcome. Each step up of the SR fuses has led to improved sound in my system. 

Frank, 
It's really impressive the large number of people your thread has exposed to the merits of premiun fuses. The list of satisfied listeners  continues to grow.
